“Such effects watch for a particular event that would happen and completely or partially replace that event with a different event.”


“Such effects watch for a particular event that would happen and completely or partially replace that event with a different event.”

They look to the future

Event? “Anything that happens in a

game is an event. Multiple events may take

place during the resolution of a spell or ability.

The text of triggered abilities and replacement effects defines the event they’re looking for.”

Event

How many counters?

Event

NOT “Enters with a +1/+1 counter” + “Enters with two +1/+1 counters”

BUT “Enters the battlefield” → “Enters the battlefield with a +1/+1 counter” → “Enters the battlefield with three +1/+1

counters”

Replacement effects are not events, they modify events.

Event Replacement effects affect an event only

once

use the word

instead now)

How to determine which to apply?

The affected player chooses Some replacement effects have to be

chosen above others

Order

1. “Self-replacement effects”

Order

2. “Modify under whose control an object would enter the battlefield”

Order

3. “Cause an object to become a copy of another object as it enters the battlefield”

Order

4. “Any”

Order1. Self-replacement

2. Control-changing

3. Copy

4. Any

Once one replacement effect is chosen, the game rechecks which replacement effects are applicable

4. Interaction with other rules

1. Can't

2. Effect

4.1 Can't An event that can't happen cannot be

replaced

4.1 Can't An event can be replaced with an event

that can't happen

4.2 Effect “An effect is something that happens in

the game as a result of a spell or ability.”

4.2 Effect? “I’ll probably be

changing that rule for a future update. If this goes as planned, after that update you’ll double the counters on Gemstone Mine, Vivid lands, etc.”

5. Entering the battlefield

Stack Battlefield

1. No in-between state

2.Replacement effects look to the future

Stack BattlefieldPretend Zone

5. Entering the battlefield Characteristics not like either zone

5. The Blind Eternities

The Æther between the planes “In this chaotic, surreal expanse

of uncontained energy and matter, time, distance, and the senses have little meaning.”

Graveyard BattlefieldBlind Eternities

So what are the characteristics of a card in the blind eternities?


1. The card is still in the old zone


...and it can be chosen for replacement effects


...but it's not affected anymore by continuous effects that would affect it there

Stack BattlefieldBlind Eternities

2. It pretends to be on the battlefield, but only for its own continuous effects


...and not as an entire card


...and once again, other continuous effects aren't applied


3. One exception: continuous effects from resolved spells or abilities that changed the card's characteristics on the stack


4. Earlier replacement effects are taken into account


… and continuous effects can affect replacement effects

Battlefield

Blind Eternities

5. It's own replacement effects only work if they only affect itself

Stack

Summary of 614.12

When entering the battlefield, a card's characteristics are determined by:

1. Earlier replacement effects

2. Resolved changes on stack

3. Own continuous effects as if it were on the battlefield

It's own replacement effects apply if they affect only itself


...and this is checked for each card individually!


So what happens?

Can't traverse the Blind Eternities

So what happens?

The end... almost!

Anafenza

“Anafenza’s last ability cares only what the card would be in the zone it’s moving from, not what it would be in the graveyard.”

Anafenza “In the text of spells or abilities, the term

“card” is used only to refer to a card that’s not on the battlefield or on the stack, such as a creature card in a player’s hand.”

?The End!

Can't traverse the Blind Eternities

“that continuous effect applies simultaneously with the permanent entering the battlefield.”
